i itation filed a 18,1922. Serial uo. 5s1,5s5.

To all whom it may concern:

Be it known that I, GEORG E. CoLnMAN,

a citizen of the United States, and a resident of the city and county of SanFrancisco, in the State of California, have invented a new and useful Household Mixer and Beater, of which the following is a specification.

This invention relates to a device for mixing or beating various articles of food in the household; and especially to a device adapted for such uses as beating eggs, whipping cream, or mixing salad dressings.

It is an object of my invention to provide an extremely simple and inexpensive motor driven device for such uses, that is light in weight and inexpensive in construction.

Another object of my invent-ion is to pro vide-a simple household device for operating on various articles of food so arranged that it can rest in a substantially upright position upon a surface such as the bottom of a container while in operation, without the need of any further support.

My invention possesses other advantageous features, some of which with the foregoing will be set forth at length in the following description, where I shall outline in full that form of the invention which I have selected for illustration in the drawing accompanying and forming part of the present specification. In the drawing I have shown but one embodiment of my invention but it is to be understood that it is not limited thereto since the invention as expressed in the claims may be embodied in other forms as well.

Referring to the drawings:

The single figure is a perspective view showing the device ready for use.

The device may comprise a source of power such as a small electric motor 1, and a support 2 attached to the motor frame, for permitting the device to be placed in an upright position in a pan or dish containing the material to be beaten or mixed, The

' support 2 may conveniently be made of a base ring 3, connected by strong strips or bars 4. to boss 5 attached in any appropriate manner to the motor 1. These strips t are shown as fastened by the screws 6 to the boss 5. They are bent to form hooks embracing the ring 3 at their lower ends, and the fastening may be made still more secure by using solder. They thus form a substantially symmetrical support for the device,

the shaft 7 such as by manual exertion. To this shaft is attached, in any appropriate manner, an extension member 8, carrying at. its lower end a flat disc or wheel 9. This disc forms the heating or mixing member and is located centrally of the supporting ring 3 near enough to-itso that it can reach substantially to the bottom of the material to be mixed or beaten.

I have found that by perforating this member 9 with holes 10 having their axes substantially parallel with that of rotation, it is possible to beat eggs, whip cream or perform like operations with little expenditure of energy and within a time considerably shorter than with other types of apparatus. It is not entirely clear to me why the provision of the apertures 10 should produce this beneficial result. I believe, however, that it is due to the cutting action of the edges of apertures 10 upon the material in combination with the creation of rapid pressure variations. This when accomplished at a fairly rapid rate, mixes the material very eliiciently and practically without noise or undue vibration of any kind. The motor 1 is shown as of the type disclosed in my copending application, Serial No. 531160, filed Jan. 23, 1922, and en titled Dynamo-electric machine, An appropriately pivoted handle 11 may be provided on the motor frame to facilitate manipulation. Since the entire weight of the device is distributed substantially evenly about the vertical axis, there is no difliculty in resting it upon the ring 3 in the position shown in the drawing. Due to lack of disturbing vibration, the device may be safely operated in this position.

I claim:

1. In a household device, a source of motive power, a shaft extending from. the source and adapted to be rotated thereby, and means for supporting said device in a substantially upright position for operation comprising a plurality of strips each attached at one end to the source of power.

and a member attached to the other ends of the strips, the strips and said member forming a substantially symmetrical arrangeinent. about, the extending shaft, and hav1ng.. an

axis of symmetry substantially coinciding with the axis of the shaft. 7

2'; In a household-device, asource of motive power, a shaft extending from thesource and adapted to be rotated thereby, a flat member attached to the shaft'so as to extend a substantial distance from the source of POWQI,&I1C1L adapted to be used for operating upon. various articles -of food for.

changing the condition thereof 'by-being rotated therein, and means forsupporting said L device in a'substantially upright position upon a surface for operation comprising a plurality ofstripseaeh attached at one end to the sourcefotpower, and la supporting member attached to the other; ends qofij the strips and: mpass ng... he. fiat p r ting,

member, said. supporting: member being adapted to rest on a surface and to maintain theoperating member near said surface.

3?. In a device adapted to be utilized for changing the condition of food by agitation,

a source of motive power, a shaft driven by member, said ring serving as a base forthe.

device and. disposed near to the. operating member, whereby it maybe placed Within a receptacle along With thejoperatingmember, and means for supportingthe source of power upon said ring,
